Magnetite Definition Magnetite is a brown to black mineral that is strongly magnetic It crystallizes in the cubic system and commonly occurs as small octahedrons Magnetite occurs in many different types of rock and is an important source of iron Its chemical formula Fe 3 O 4 and it is one of the oxides of iron Magnetite is very easy to

Magnetite and hematite are common ironoxides being found in sedimentary metamorphic and igneous environments and being associated with a wide variety of deposits styles including orogenic gold ironoxide coppergold and ironore deposits While the magnetic and mass properties of magnetite and hematite have been

Many of magnetite’s applications are possible because of its strong magnetism intense black colouration abundance affordability and high iron content Applications of Magnetite Oxide Due to its high iron content and availability magnetite is widely used in the production of iron and steel as well as in water purification processes

compositiondependent magnetic parameters of a variety of ironbearing minerals 2 MAGNETIC SUSCEPTIBILITY Magnetic susceptibility is a measure of the magnetic response of a material to an external magnetic field The volume susceptibility k measured in dimensionless units is defined as the ratio of the material magnetization J per unit

On roasting it is readily transformed into the magnetic sulphide and on the continuation of the roast into a strongly magnetic oxide analogous to the mineral magnetite Pyrite in some specimens on being heated at a quite low temperature for a minute or two develops an iridescent film of magnetic sulphide which imparts sufficient

balance experiments The magnetic monitoring of the alteration of pyrite with temperature shows that at about 500°C magnetite always appears and can alter afterwards to hematite depending on the experimental conditions Therefore an increase of magnetisation due to the magnetite suggests the presence of pyrite in the studied samples

The magnetic minerals most commonly identified by these techniques are magnetite goethite hematite and maghemite These magnetic minerals occur in different combinations in the marine limestones of central Europe and the Mediterranean realm Pyrite is common in certain limestones where it can be the precursor of an unwelcome late goethite

Magnetite ideal formula Fe 3 O 4 is an intriguing mineral not only because it is formula could be written as Fe 2 Fe 3 2 O 4 which more precisely designates one of its contains both ferrous Fe 2 and ferric Fe 3 ions implying synthesis growth and stability within an environment where oxidized and reduced states of iron are present and maintained

Magnetite is a form of iron oxide Fe 3 O 4 which possesses uniquely iron in both the Fe 2 and Fe 3 oxidation states Bearing the form of an inverse spinel it’s magnetic properties are highly valued Addition of magnetite to soil is advantageous as it can later be removed easily by using magnets It can occur naturally in soil or be added as a soil treatment agent
